Application filed November 5, 1920. Serial E0. 42 2,4383.

To all whom it may concern:

Be it known that I, ALFRED H. SMITH, acitizen of the United States,residing at the city of New York, county of N ew' York, and

State of New York, have invented certain new and useful Improvements inInterchangeable Gar Units, of which the followin is a description.

i/Iy invention relates to means for trans porting and handling less thancar load lots of freight, express and the like, by railroad car, truck,barge or other carrier.

According to-my invention a carrier, such as a railroad car, truck,barge or the like, is adapted to receive and carry a plurality ofcontainers each handling less than removabiy and interchangeablypositioned on the carrier frame, shifted to and from the and destinationstations.

According to my invention the containers may be loaded by the shipper athis factory then carried by truck to the railroad car and loaded thereonand at the point of destination lifted from the railroad car onto atruck anddelivered at the place of business of suitable capacity for ofthe consignee who may remove the contents therefrom whereupon thecontainer is returned to and loaded on the railroad car either empty orloaded. 4

One of the objects of my invention is to provide the railroad car,truck, bargeor the like, withmeans to lock the container thereon andprovide the container with cooperating locking means whereby the twolocking means interlock when the container is lowered into position onthe carrier.

For brevity I shall use theterm carrier to include railroad cars, motiveor horse drawn trucks, barges, etc; 9

With. the above and other objects in view my invention consists of thenovel features of construction and arrangement of parts, hereinaftermore fully described and claimed. r

In the drawings:

F igure 1 is a side elevation of the end portion of arailroad car or,carrier and containers mounted thereon.

Figure 2 is a top plan view of the same.

Figure 3 is an enlarged detail view showingthe locking means for thecontainers.

Figure 4 is a detail sectional-view on the line H of Figure 3.

Figure 5 is a detail top plan view of the carload lots, which are andmay be readilycarrier at receiving sills 12,

of the ears 24: of

locking means, the car or carrier being broken away. a

Figure 6 is a perspective Wiew of the locking dogs detached.

The reference numeral 5 designates a. carrier and 6 a container whichmay be of any suitable construction, the containers being designedpreferably to hold less than car load lots, there being a plurality ofcontainers for the carrier which containers may be billed to differentdestinations route laid out for the carrier.

At the lower corners of the containers 1 secure suitable castings orforgings 7 by rivets or otherwise, said castings being provided withdepending members which may function as legs 8, which legs are providedwith outwardly projecting lugs 9 each of which on the on I stantiallymidway the length of the legs, the sides of the legs below the lugspreferabl converging as shown in the drawing.

Sitake pockets 11 are secured to the side and are adapted to receivepending legs 8 of the containers when the containers are loaded on thecar. These stake pockets are provided with perforated lugs or earsj 13to which the locking dogs 14 are by means of the bolts or pintlesv 15,

which pintles are locked in position by means of cotter pin 16. Thelochng dogs areLsubstantially bell crank in shape, one arm 17 beingrovided with adapted tointerlock over the lug 9 on the flat shoulder 10,while the other arm 19 is provided at its free end with a recess orcutout 20 having a half bolt opening 21 in'one of its walls so that whendogs are moved to locked position (Figures 1, 3 and 4:) the openings 21register and form a compl bolt, opening which is adapted to refit: thelocking bolt 22 which is secured to carrier by 23 to prevent its beinglost.

It will be noted from Figure 4 that one the locking dog is spaced fromthe other whereby the arm 19 of the the deso pivotally secured on a hook18 no the two looking as means of a chain mo dog is spaced from the sideof the cairier m5 and is free to swing outside the outer face I of thepocket .11. The ends of the arms '19 to move the dogs and consequentlythe container is securely locked on the carrier.

Similar locking means are provided on the truck whereby the container issecurely locked thereon while 'it is being transported to and from thecarrier or car.

What I claim is:

1. In afreight car the combination with a series of compartmentsremovably mounted thereon, legs depending from said compartments, lugson said legs and dogs pivotally secured to the car and adapted tointerlock with said lugs and lock the compartments on the car. 7

2. In a freight car, the combination with a series of compartmentsremova-bly mounted thereon, legs depending from said compartments, lugson said legs, a series of pairsof dogs pivotally mounted on the car,each pair of dogs being adapted to engage the lugs on each of said legs,whereby the compartments are locked to the car.

3. In a freight car, a series of pockets secured to the ear, -a pair oflocking dogs mounted on each pocket, a series of compartments removablymounted on the car, legs depending from said compartments, and adaptedto enter the saidpockets, said locking dogs engaging said legs therebylocking the compartments on the car.

4. In a freight car a series of pockets secured to the car, a pair ofbell crank shaped locking dogs secured to each pocket, one of the armsof each lever overlapping the other and means locking said overlappedarms when the dogs are in operative position.

5. In a freight car, a series of pockets secured to said car, a pair ofhell crank shaped dogs pivotally mounted on eachpocket so that one armof each dog will overlap a cor-- responding arm of the other dog whenthe dogs are in operative position, a recess in each overlapped arm andabolt adapted to enter said recesses when the dogs are in operativeposition, thereby locking the dogs in their operative position.

6. In a freight car, a series of pockets sccured to-the car, a series offreight compartments removably mounted on the car, legs on saidcompartments adapted to enter said pockets, lugs on said legs, a pair ofhell crank shaped dogs pivotally mounted on each pocket so that one armof each dog will overlap a corresponding arm of the other dog when thedogs are in operative position in which position the dogs engage thelugs on. the said legs and lock the compartments to the car, a recess ineach overlapped arm and a pin adapted to enter said recesses when thedogs are in operative position, thereby 0 locking the dogs in theiroperative position.

In testimony whereof I aflix my signature.
